Instead, generate bytecode to execute their AST nodes and save the resulting operands inside the NewClass instruction. Moving property expression evaluation to happen before NewClass execution also moves along creation of new private environment and its population with private members (private members should be visible during property evaluation). Before: - NewClass After: - CreatePrivateEnvironment - AddPrivateName - ... - AddPrivateName - NewClass - LeavePrivateEnvironment
